Question

1. solve for x (12x)° 30° x = ______

Explanation:

Step1: Identify angle - relationship

The two angles are complementary, so their sum is 90°.
$12x + 30=90$

Step2: Solve for x

Subtract 30 from both sides: $12x=90 - 30$, so $12x = 60$.
Then divide both sides by 12: $x=\frac{60}{12}$.

Answer:

$x = 5$
